Effect of Fluoride in a Dentifrice on Remineralization of Erosive Lesions

The Effect of Fluoride in an Experimental Dentifrice on Remineralization of Erosive Lesions In-Situ

The proposed study will evaluate the performance of fluoride delivered from a new dentifrice formulation without potassium nitrate. It will also evaluate the dose-response to fluoride by testing four dentifrices covering a range of sodium fluoride concentration.

Inclusion Criteria:

• intact maxillary dental arch suitable to retain a palatal appliance, an intact mandibular dental arch and a stimulated/unstimulated saliva flow rate of ≥ 0.8 milliliter/minute (ml/min) and ≥ 0.2 ml/min respectively.
